"Xinjiang" or "Ice Jecen" in Manchu, literally means "New Frontier", a name given during the ManchuQing Dynasty in China. It is home to a number of Turkic ethnic groups, the largest of which are the Uyghurs. Historically, in the West, the Xinjiang area has sometimes been known as Chinese Turkestan or East Turkestan.

Xinjiang is divided into 2 prefecture-level cities, 7 prefectures, and 5 autonomous prefectures. (2 of the 7 prefectures are in turn part of Ili, an autonomous prefecture.) Below them, there are 11 districts, 20 county-level cities, 62 counties, and 6 autonomous counties. Four of the county-level cities do not belong to any prefecture, and are de facto administered by the Xinjiang Production and Construction Corps.

Xinjiang is the largest political subdivision of China - it accounts for more than one sixth of China's total territory and a quarter of its boundary length. It is divided into two basins by Mount Tianshan. Dzungarian Basin is in the north, and Tarim Basin is in the south. Xinjiang's lowest point is 155 metres below sea level (lowest point in the PRC as well). Its highest peak is 8611 metres above sea level on the border with Kashmir.

Most of Xinjiang is young geologically, having been formed from the collision of the Indian plate with the Eurasian plate, forming the Tian Shan, Kunlun Shan, and Pamir mountain ranges. Consequently, Xinjiang is a major earthquake zone. Older geological formations occur principally in the far north where the Junggar Block is geologically part of Kazakhstan, and in the east which is part of the North China Craton.

Xinjiang has within its borders the point of land remotest from the sea (Lat. 46 degrees 16.8 minutes N, Long. 86 degrees 40.2 minutes E) in the Dzoosotoyn Elisen Desert, 1,645 miles (2648 km) from the nearest coastline (straight-line distance).

Xinjiang's nominal GDP was approximately 187 billion RMB (about 23 billion USD) in 2003, and increased to 220 billion RMB in 2004, due to the China Western Development policy introduced by the State Council. Its per capita GDP for 2003 was 9,710 RMB (1172 USD).

Xinjiang's exports amounted to 3.047 billion USD, while import turned out to be 2.589 billion USD in 2004. Most of the overall import/export volume in Xinjiang was directed to and from Kazakhstan through Ala Pass [1]. China's first border free trade zone (Horgos Free Trade Zone) was located at the Xinjiang-Kazakhstan border city of Horgos [2]. Horgos is the largest land port in China's western region and it has easy access to the Central Asian market. Xinjiang will also open its second border trade market to Kazakhstan in March 2006, the Jeminay Border Trade Zone. [3]

The percentage of ethnic Han Chinese in Xinjiang has grown from 6 percent in 1949 to an official tally of over 40 percent at present. This figure does not include military personnel or their families, or the many unregistered migrant workers. Much of this transformation can be attributed to the Xinjiang Production and Construction Corps (XPCC), a semi-military organization of settlers that has built farms, towns, and cities over scattered parts of Xinjiang. The demographic transformation is held by Uyghur independence advocates as a threat to Uyghurs and other non-Han ethnicities in maintaining their culture, similar to the case of Tibet.

Some Uighur scholars claim descent from both the Turkic Uighurs and the pre-Turkic Tocharians (or Tokharians, whose language was Indo-European), and relatively fair-skin, hair and eyes, as well as other so-called 'Caucasoid' physical traits, are not uncommon among them. In general Uyghurs resemble those peoples who live around them in Afghanistan, Kyrgyzstan, Uzbekistan, Kazakhstan, and Pakistan.
In 2002, there were 9,632,600 males (growth rate of 1.0%) and 9,419,300 females (growth rate of 2.2%). The population overall growth rate was 10.9‰, with 16.3‰ of birth rate and 5.4‰ mortality rate.
